RADIATOR-VALVE.

JPBCIPICATION forming part; of Letters Patent No. 320,813, dated June 23, 1885.

Application filed May 9, 1854. (No model T0 at whom it may concern.-

Be it known that I, W. BAIRD PATTON, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minncsota, have invented certain new and useful Improvements in Radiator-Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, refer ence being bad to the accompanying drawings, which form part of this specification, in which- Figure l is a sectional plan, and Fig. 2 a sectional elevation, of valve. Figs. 3, 4, 5, and 6 are detail views of valve-shaft, arms, and wings. Fig. 7 is an elevation of radiator with valve. Fig. 8 is a sectional plan, and Fig. 9 a sectional elevation, of valve combined with base of radiator. Figs. 10 and 11 are modified arrangements in views similar to Figs. 8 and 9. Figs. 12 and 13 are details of modifications.

My invention has for its object to provide means for the regulation of the admission of steam into a radiator by the use of a single valve.

I My invention consists in the peculiar con struction and combination of parts hereinafter fully specified, having reference, principally, to avalve having two or more seats and ports, and a stem or shaft with two wings, adapted to change the communication between such arts, ashereinafter set forth.

Referring to the accompanying drawings, Fig. 1 shows a sectional plan of a valve of a form to be used in connection with radiators constructed as heretofore for using two valves, having openings for the supply and return pipes at the opposite ends or at the same end.

A shows the opening for the steam-supply pipe, and may be either in the bottom, side, or top of the body of the valve.

B shows the opening for the return-pipe, and may be either in the side or bottom of the valve. If in the side it should be as near the bottom as possible.

0 represents the shaft of the valve, to which are attached two arms, a c, carrying two wings, 0'0 which are made so as to exactly fit the openings d d e e, and to seat steam-tight on the seats of said openings. Said wings may be made of the form shown in elevation 1n Fig. 3, and in plan, Fig. 4, having beveled.

edges on both sides, or, as shown in Fig. 5, having only one edge of each beveled, and may be made rectangular, as shown in the drawings, or, preferably, circular or oval. The openings (1 d e e in the diaphragms D E should be made to correspond in shape and dimensions with the wings of the valve. The diaphragms D E may be cast with the body, or they may be made separately and afterward attached to said body, so that they can be removed for repairs.

Fig. 2 shows a sectional elevation of the valve on the line 00 y of Fig. 1. O is the ban dle of valve-shaft G, and c is a stuffing-box through which shaft 0 enters the body. F F are offsets in the diaphragms D E, to receive the arms 0 0.

The operation of the valve is as follows: It being desired to admit steam into the radiator, the-handle of the valve is turned so that the wing c closes the opening d, the wing c at the same time closing the opening d. The steam then enters at the opening A, passes through the openings e and g, and thence to the radiator. The returning steam and condensation enter the valve through the opening it to the opening B, and thence to the boiler.

It being desired to shut off steam from the radiator, the handle is turned, bringing the wing 0 to fill the opening 6, the wing a" filling the opening a. The steam then entering at the opening A passes through the opening 01 and thence to the boiler by the opening B.

Fig. 7 shows the manner of connecting this valve with the ordinary radiators. The supply of steam passes through the pipe G to the valve H, thence by the pipe I to the radiator through an inlet in the base of the latter. After passing through the radiator the return passes out by the pipe K to the valve H, thence by the pipe L to the boiler.

A modified form of valve-shaft, arms, and wings, shown in plan in Fig. 6, Iconsider preferable to the other forms. The wings in this form may be made rectangular, circular, oval, or rectangular with rounded or beveled corners, and are composed of four detachable pieces 0 c c" 0 which are attached by means of bolts to the arms 0 0, as shown. The advantage of this form is that if anything should happen to the wings they can be removed, replaced, or repaired.

Fig. 8 is a sectional plan, and Fig 9. a sectional elevation, of the valve above described, combined with the base of a radiator. M is the opening for the steam supply, and N the opening for the return. R is the base of the radiator, which is to be made with afall in the direction of the valve. The wings of the valve in this case will only need two disks or true surfaces, as the openingsr r are the only ones to be filled. The valve in this case may be made, as shown in Fig. 5, or asin Fig. 6, with two of the disks 0 and c removed. The mode of action is as follows: No steam being desired in the radiator, the handle is turned so that the wing c'fills the opening r, and the wing c the opening 4 The steam entering by the opening M passes out by the opening N without reaching the radiator. It being desired to admit steam, the handle is turned until the wings are about in line with the axis of the radiator; the steam then has free access to every part of the radiator, and the condensation returns to the valve end of the base on account of the fall in that direction, and passes out by the opening N.

Figs. 10 and 11 show another form of radiator base in connection with the above described valve. Fig. 10 is a sectional plan, and Fig. 11 a sectional elevation. In this case the valve-wings are double, each closing tWo openings. The base of the radiator is to be cast with a partition running through it to within a short distance of the end, and having openings for the wings of the valve. The base is also cast with a fall from the point W to the point V, as indicated by the arrows in Fig. 10. The point W on the same side of the partition as the steam is admitted is the highest point. The wings of the valve may be constructed in any of the forms hereinbefore described. When it is desired to admit steam, the valve is turned so that the wing c fills opening (1 and wing c fills opening d. The steam,then passes, asindicated by the arrows, through the openings 25 and e to the opening B and back to the boiler, and this will, of course, be the route taken by all of the water of condensation.

WVhen it is desired to shut off steam, the valve is turned until the wing 0 fills opening 6 and wing c fills opening 6. The steam then entering by opening A passes through open ings d B back to the boiler. The object of this mode of constructing it is to secure a positive circulation of steam from the inlet to the outlet, thus obviating the necessity of the water of condensation returning against the pressure of the steam, as it does in the form shown in Figs. 8 and 9.

The wings of the valve may be made with rounded edges, as shown in Fig. 13, or rabbeted, as shown in Fig. 12, the valveseats being made to correspond.

What I claim as my invention is as follows:

1. A radiator-valve consisting of a suitable casing through which passes a shaft carrying wings set at diametrically opposite points thereon, said casing being provided with two or more partitions with openings having valveseats adapted to be closed by said wings, substantially as described.

2. A radiator valve-body having inlet and outlet ports and two diaphragms dividing the interior of the valve into four chambers, said diaphragms being provided with openings and valve-seats, in combination with a shaft carrying wings adapted to fit said seats and openings, and to change the direction of passage of steam through the valve, substantially T as shown and described.

3. The combination, with a radiator, of a single valve for regulating the admission of steam, said valve comprising a shaft carrying wings and a body having inlet and outlet ports and a diaphragm with seat-openings opened and closed by said wings, substantiallyas shown and described.

4. The combination, with a valve-casing having internal diaphragms with openings forming seats'for valves, of a shaft having arms 0 c, which carry detachable valves 0 0, adapted to fit the said openings, substantially as described.

In testimony that I claim the foregoing I 100
